SINK-STRAINER.

Specification of Letters Patent.

Patented Mar. 1, 1910.

Application filed February 28, 1907. Serial No. 359,762.

To all whom it may concern:

Be it known that I, John Mexican, a subject of the King of l h'igland,residing in the city of \Vcst Orange, in the county of Essex and Stateof New Jersey, have in vented certain new and useful Improvements inSink-Strainers, of which the following is a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it pertains and to which it most nearly relates to make,construct, and use the same.

The object of my invention is to provide a strainer for use in kitchensinks, for the purpose of catching refuse or waste substances whichaccumulate in the sink and would otherwise clog up the traps and drainpipes, such refuse being caught upon the surface of the strainer andthence removed for purpose of cleaning.

In carrying out my invention, I make use of a structure substantially asillustrated in the accompanying drawings, in which Figure 1 is a planview of my strainer, showing a scraper held beneath the handle of thesame. Fig. 2 is a cross-section of a sink showing the strainer inposition over the discharge pipe, and also showing one form ofconstruction. Fig. 3 illustrates a modification, and Fig. 4 illustratesanother modification.

Similar characters of reference refer to like parts throughout thespecification and drawings.

The strainer body consists of a sheet of perforated meta], preferablytin or galvanized sheet iron as 1, having its edges turned over to forma double fold 2 as shown at the edge in Fig. 2. Vithin the fold 2 whichopens outwardly, I insert a strip of rubber, fabric or any othersuitable material 3, which is flexible and impervious to liquids, andwhich, when in osition, will flex down- I wardly as illustratec indotted lines in Fig.

2, under the pressure of water flowing through the strainer.

The strainer as illustrated in Fig. 2 is placed in a sink 9 over thedrain pipe 10 as shown, and all accumulations of greasy substances orparticles contained in the dish water are caught upon the surface of thestrainer, while the water is drained off, the flexible margin 3, whilethe water is draining away, forming a practically water-tight connectionbetween the margin of the strainer and the bottom of the sink, so thatall of the water is forced through the perforations in the strainer.

I have shown in Fig. 1, a handle t secured in any convenient manner, asby means of the clips 5, which are soldered to the upper face of thestrainer. This handle ll forms a convenient means for lifting andcarrying the strainer. It also forms a convenient means for securing thescraper G, which, when the accumulations are all caught and the waterdrained away, may be used for scraping the accumulations from thesurface of the strainer into the garbage pail or other receptacle.

In Fig. 3, I have shown a modification, in which the strips of rubberare secured to the underside of the margins of the strainer in adifferent manner. In this case, strips of U-shaped metal 7 are used togrip the margin of the rubber, such strips afterward being soldered tothe under side of the strainer as shown. The operation of the modifiedform, however, is identical with that described in connection with Figs.1 and 2.

In Fig. l, I have shown still another modification, in which the stripof rubber 3 is held to the edge of the strainer by means of a singlestrip of metal 8 forming a channel in connection with the edge of thestrainer, as shown. This strip of metal is so dered or otherwise securedto the margin of the metal, somewhat remote from its extreme edge, sothat the free edge of the strainer in connection with the free edge ofthe strip of metal, forms a gripping means for the edge of the rubber.In operation, this 1nodilication is identical with the other two doscribed.

In all of the forms illustrated, the means for securing the f exiblefabric to the margin of the perforated metal, being of considerablethickness, serves to elevate the sheet of perforated metal above thesink bottom and thereby presents a larger aggregate exit for the waterthan would be afforded by the partially clogged permanent straineralone, inasmuch as the accumulation can not clog the entire surface ofthe perforated sheet while it would quickly clog the permanent strainer.

I do not wish to limit myself to the use of a strainer of rectangularoutline as illustrated in the drawings, as an oval or circular shapewould be equally effective in operation, the principal feature residingin securing to the margins of the perforated strainer, a strip offlexible fabric, which by its val-velike action, forces all of thewater, with its accumulations, upon and over the surface of thestrainer, whence the water is drained off and the accumulations caught,to be afterward disposed of.

In order to form a support for the center of the strainer in case thesame should have a tendency to bend downwardly under the weight ofsuperposed dishes, or any external Weight and also for the purpose ofform ing, what I term, suckers, to retain the strainer in position, andprevent the same from shifting about when in position, I provide on theunder side the series of supports or suckers 11, clearly illustrated inFig. 2. These suckers or supports may be of any material, as forexample, rubber, leather or any fabric whatever, which will serve thepurpose of a support or act in such a manner as to prevent the shiftingof the strainer when once placed in position, for the reason that theyadhere closely to the sink bottom and their adhesion is increased bytheir being wet.

I claim: 1. In a sink strainer, the combination of a sheet of perforatedmetal, a strip of fieXi ble material, means for securing said flexiblematerial to the margin of said sheet of metal and to hold the body ofsaid sheet of metal above the bottom of a sink.

2. In a sink strainer, the combination of a sheet of perforated metalwith a strip of flexible material secured to its margin, and a series ofmembers secured to the lower face of said perforated metal, to hold thebody thereof above the sink bottom and to prevent its shifting.

3. In a sink strainer, the combination of a sheet of perforated metal, astrip of flexi ble material secured to its entire margin on its underside and projecting beyond the edge of said sheet, and a series ofmembers secured to the lower face of said perforated metal, to elevatethe body of said strainer above the bottom of the sink and to prevent itfrom shifting.

This specification signed and witnessed this 26th day of February, 1907.
